I have a create train with the chuck loader on it traveling between the overworld and the nether. When the train goes through the portal the chunk loader stops working. it's supposed to fill with lava and return to the overworld through a second portal. The train itself travels from dimension to dimension normally, but the pump that fills it with lava doesn't load so the train returns to the overworld with an empty tank. The train system also works perfectly when I ride it as a passenger.

Minecraft: 1.18.2 Create: 0.5 CreateChunkloading: 1.2.1

I am not sure if I can get the chunkloader to work with unloaded trains. As far as I know, for performance reasons, the trains stop acting as entities once they move into unloaded chunks and are just simulated by Create.

I can look into this at some point, but it will be a while.

Can you not just reactivate the chunkloader a few seconds after it travels through the portal? Or is Create's code written in such a way that there has to be a player there before you can tell the train to act become an entity again, or maybe some other restriction?

the thing with adding chunk loaders on trains is that trains are specifically designed to not need chunks loaded, making them feasible for long distance transport on servers. you can just put chunk loaders at the stops where loading is necessary, and you'll probably be doing that anyways to allow your factories to function while the train is away
